Eaton 657GREEN EMT compression connector - NEC/CEC
Part Number: 657GREEN
Quick Summary
The Eaton Crouse-Hinds EMT compression connector 657GREEN is a rugged EMT fitting for industrial control panels and heavy machinery enclosures. Many projects struggle with slow installs, misaligned terminations, corrosion risk, and inconsistent identification across multiple shifts, trucks, and contractor teams. It meets NEC/CEC standards and is rated for ordinary/non-hazardous locations, with UL Canada certification references available for audits and cross-border work. For engineers and procurement teams, the 657GREEN enables faster, tool-free compression, lowers field callbacks, and supports scalable, compliant electrical infrastructure with durable steel construction and color‑coded safety identification.

Feature: Compression and straight alignment streamline EMT terminations, reducing install time and torque concerns. This minimizes startup delays and ensures a durable ground path in control panels. Application: Panel wiring in OEM equipment hides the complexity of conduit routing while maintaining code compliance and a tidy enclosure layout. Business Impact: Faster commissioning, fewer reworks, and improved reliability across manufacturing lines. Feature: Threadless, non-insulated design avoids threading misalignment and simplifies retrofits in tight spaces. Application: Retrofit projects and busy shop floors where space is at a premium. Business Impact: Reduced tool dependency and maintenance time, enabling installers to complete runs with consistent results. Feature: Green color and 3 in trade size match standard EMT conventions. Application: Industrial facilities requiring rapid identification and compatibility with existing EMT runs. Business Impact: Minimizes mis-matches, accelerates procurement, and supports standardized plant aesthetics and safety labeling. Feature: Steel construction delivers robust mechanical strength and resistance to vibration in dynamic environments. Application: Control cabinets, machine enclosures, and outdoor or semi-exposed installations. Business Impact: Longer service life, lower replacement costs, and fewer field failures. Feature: NEC/CEC compliance with Ordinary/Non-Hazardous Location rating and UL Canada certification references. Application: North American facilities with cross-border projects and audits. Business Impact: Reduced regulatory risk, smoother approvals, and faster project sign-offs.

FAQs
657GREEN uses a threadless compression connection for EMT conduit, enabling tool-free installation with standard hand tools within minutes. It is designed for straight conduit runs and aligns with common EMT sizes, reducing misalignment and the need for thread seals. The robust steel construction provides a secure, enduring bond that resists vibration in panel and cabinet assemblies.
Key specs include a 3 in trade size, non-insulated steel construction, and a straight compression style. It complies with NEC/CEC standards and is rated for ordinary/non-hazardous locations, with UL Canada certifications available. The connector supports reliable grounding and mechanical integrity in control panels, switchgear, and equipment enclosures.
Best suited for industrial environments using EMT conduit in ordinary locations, such as control panels, machine enclosures, and OEM equipment housings where fast visual identification is beneficial. Its 3 in trade size matches standard EMT fittings, and the straight compression design keeps runs neat and code-compliant in manufacturing plants and distribution centers.
The connector adheres to NEC/CEC standards and is rated for Ordinary/Non-Hazardous Locations. UL Canada certification references are available for cross-border use, supporting audits and supplier qualification. Comprehensive datasheets and catalog pages are provided to streamline validation during procurement and engineering reviews.
Tool-free compression reduces installation time and field callbacks, cutting labor costs. Durable steel construction resists wear in busy facilities, lowering replacement and maintenance expenses. Access to CAD models, catalogs, and datasheets accelerates design reviews and project delivery, delivering faster time-to-value for capital projects.
